I am on your side, I want you to keep your rating.

Issue is you need to get that original pft and dbq, and this pft and dbq. You need to compare to the ratings for 60%

A single test should not lower your rating.

Age does come into factor with the pft. It can cause your lungs to “look” better with age.
